    <title>Description</title>

    <para><command>systemd-cgls</command> recursively shows the
    contents of the selected Linux control group hierarchy in a tree.
    If arguments are specified, shows all member processes of the
    specified control groups plus all their subgroups and their
    members. The control groups may either be specified by their full
    file paths or are assumed in the systemd control group hierarchy.
    If no argument is specified and the current working directory is
    beneath the control group mount point
    <filename>/sys/fs/cgroup/</filename>, shows the contents of the
    control group the working directory refers to. Otherwise, the full
    systemd control group hierarchy is shown.</para>

    <para>By default, empty control groups are not shown.</para>
